As Marshmello and Bastille hold at the top spot for a second week with “Happier”, there are three songs entering the chart, led by “Party For One” from Carly Rae Jepsen at #36. She’s led my personal chart with a pair of releases: 2012’s “Good Time” (with Owl City) and 2015’s “I Really Like You”. Her last top 40 entry, 2017’s “Cut To The Feeling”, peaked at #8. A notch below Jepsen, with her fourth title to chart this year, Ariana Grande climbs aboard at #37 with “Thank U, Next”. The song, which was released last Saturday night, holds at #1 on digital services such as Apple Music, iTunes and Spotify. It also enters the top 40 on this week’s Top 40 radio chart. Finally, at #39, the Backstreet Boys return with “Chances”, which follows their #1 single of earlier this year, “Don’t Go Breaking My Heart”, still riding the countdown at #31. Their latest tune impacts at the Hot AC format on Monday.
